Abstract
Description
- The invention relates to endless tracks for work vehicles, such as construction vehicles, agricultural vehicles, forestry vehicles, and other vehicles designed for other types of work in off-road conditions.
- Work vehicles, such as construction vehicles (e.g., bulldozers, loaders, backhoe loaders, excavators, etc.), agricultural vehicles (e.g., harvesters, combines, tractors, etc.) and forestry vehicles (e.g., feller-bunchers, tree chippers, knuckleboom loaders, etc.), are often equipped with endless tracks which enhance their traction and reduce pressure they apply on soft, low friction and/or uneven grounds (e.g., soil, mud, sand, ice, snow, etc.) on which they operate.
- One type of endless track comprises a body of elastomeric material (e.g., rubber) in which are embedded rigid cores (e.g., metallic cores) that extend transversally to impart transverse rigidity to the track and that guide wheels of the work vehicle that rotate in an inner area of the track.
- In this type of endless track, the wheels of the work vehicle typically induce wearing of the track's elastomeric material. For example, roller wheels of the work vehicle that roll on the track's inner side normally tend to cause rapid wearing of the elastomeric material in a zone where they roll. Such wear of the elastomeric material often results in fissures between the elastomeric material and the cores, particularly at locations where the roller wheels engage the cores and the elastomeric material. As they continue to roll on the track's inner side, the roller wheels tend to push rocks, sand, water and/or other undesirable matter between the cores and the elastomeric material through the fissures, which become increasingly larger. Over time, this contributes to a progressive loss of adhesion between the cores and the elastomeric material which can lead to the cores being poorly retained in or even removed from the track.
- For these and other reasons, there is a need to improve wear resistance of endless tracks having embedded cores.
- According to a first broad aspect, the invention provides an endless track for traction of a work vehicle. The endless track comprises a body of elastomeric material and a plurality of cores at least partially embedded in the elastomeric material. Each core comprises a pair of wings extending transversally to a longitudinal axis of the endless track, and a wheel guide comprising at least one guide projection projecting on an inner side of the endless track. Each guide projection comprises a top end and a wheel-facing side for facing wheels of the work vehicle. The wheel-facing side comprises a recess to impede passage of grit between the wheel-facing side and a portion of the elastomeric material in the recess.
- According to a second broad aspect, the invention provides a core for an endless track for traction of a work vehicle. The endless track comprises a body of elastomeric material. The core is at least partially embeddable in the elastomeric material. The core comprises a pair of wings extending transversally to a longitudinal axis of the endless track when the core is in the endless track, and a wheel guide comprising at least one guide projection projecting on an inner side of the endless track when the core is in the endless track. Each guide projection comprises a top end and a wheel-facing side for facing wheels of the work vehicle. The wheel-facing side comprises a recess to impede passage of grit between the wheel-facing side and a portion of the elastomeric material in the recess when the core is in the endless track.
- According to a third broad aspect, the invention provides an endless track for traction of a work vehicle. The endless track comprises a body of elastomeric material and a plurality of cores at least partially embedded in the elastomeric material. Each core comprises a pair of wings extending transversally to a longitudinal axis of the endless track, and a wheel guide comprising at least one guide projection projecting on an inner side of the endless track. Each guide projection comprises a top end and a wheel-facing side for facing roller wheels of the work vehicle that roll on the inner side of the endless track. The wheel-facing side comprises a wheel-contacting surface for contacting the roller wheels and a sealing surface receding inwardly from the wheel-contacting surface to impede passage of grit between the sealing surface and a portion of the elastomeric material adjoining the sealing surface.
- According to a fourth broad aspect, the invention provides an endless track for traction of a work vehicle. The endless track comprises a body of elastomeric material and a plurality of cores at least partially embedded in the elastomeric material. Each core comprises a pair of wings extending transversally to a longitudinal axis of the endless track, each wing comprising a top surface oriented towards an inner side of the endless track. Each core also comprises a wheel guide comprising at least one guide projection projecting on the inner side of the endless track. Each guide projection comprises a top end and a wheel-facing side for facing roller wheels of the work vehicle that roll on the inner side of the endless track. The wheel-facing side comprises a protrusion for contacting the roller wheels, the protrusion having a bottom edge vertically spaced from the top surface of each wing.
- According to a fifth broad aspect, the invention provides a method for reducing wear of an endless track for traction of a work vehicle. The method comprises providing the endless track with a body of elastomeric material and a plurality of cores at least partially embedded in the elastomeric material. Each core comprises a pair of wings extending transversally to a longitudinal axis of the endless track, and a wheel guide comprising at least one guide projection projecting on an inner side of the endless track. Each guide projection comprises a top end and a wheel-facing side for facing wheels of the work vehicle. The wheel-facing side comprises a wheel-contacting surface for contacting the wheels and a sealing surface receding inwardly from the wheel-contacting surface. The method also comprises moving the work vehicle such that the wheels induce wear of some of the elastomeric material, wherein, for each guide projection, the sealing surface impedes passage of grit between the sealing surface and a portion of the elastomeric material adjoining the sealing surface.
- These and other aspects of the invention will now become apparent to those of ordinary skill in the art upon review of the following description of embodiments of the invention in conjunction with the accompanying drawings.

FIG. 1 shows awork vehicle 10 in accordance with an embodiment of the invention. In this embodiment, thework vehicle 10 is a construction vehicle designed to perform construction work. More specifically, in this example, theconstruction vehicle 10 is a loader. In other examples, theconstruction vehicle 10 may be a bulldozer, a backhoe loader, an excavator, or any other type of construction vehicle. - The
construction vehicle 10 comprises aframe 12 supporting aprime mover 14, a pair oftrack assemblies implement 18, and anoperator cabin 20, which enable an operator to move theconstruction vehicle 10 on the ground and perform construction work. - The
prime mover 14 provides motive power to move theconstruction vehicle 10. For example, theprime mover 14 may comprise an internal combustion engine and/or one or more other types of motors (e.g., electric motors, etc.) for generating motive power to move theconstruction vehicle 10. Theprime mover 14 is in a driving relationship with each of thetrack assemblies prime mover 14 either directly or indirectly via a power train or other power transmission mechanism of theconstruction vehicle 10. - The
operator cabin 20 is where the operator sits and controls theconstruction vehicle 10. More particularly, theoperator cabin 20 comprises a set of controls that allow the operator to steer theconstruction vehicle 10 on the ground and perform construction work using the workingimplement 18. - The working implement 18 is used to perform construction work. In this embodiment where the
construction vehicle 10 is a loader, the working implement 18 is a dozer blade that can be used to push objects and shove soil, debris or other material. In other embodiments, depending on the type of construction vehicle, the working implement 18 may take on various other forms, such as a backhoe, a bucket, a fork, a grapple, a scraper pan, an auger, a saw, a ripper, a material handling arm, or any other type of construction working implement. - The
track assemblies prime mover 14 to propel theconstruction vehicle 10 on the ground. With additional reference toFIG. 2 , in this embodiment, each track assembly 16 i (i=1 or 2) comprises anendless track 22 disposed around adrive wheel 24, afront idler wheel 26, arear idler wheel 29, and a plurality of roller wheels 28 1-28 10. - The
drive wheel 24 is operative for driving theendless track 22 to propel theconstruction vehicle 10 on the ground. When driven by thedrive wheel 24, theendless track 22 moves along an endless path around thewheels - The
idler wheels prime mover 14 to motive force, but rather guide theendless track 22 and/or maintain it under tension as it is driven by thedrive wheel 24. Also, the roller wheels 28 1-28 10 support and distribute part of the weight of theconstruction vehicle 10 on the ground via theendless track 22. As theendless track 22 is driven by thedrive wheel 24, the roller wheels 28 1-28 10 roll on a lower run of theendless track 22 to apply it on the ground for traction. - The
track assembly 16 i may be configured in various other ways in other embodiments. For example, in some embodiments, thetrack assembly 16 i may comprise a front drive wheel (e.g., thefront idler wheel 26 may be replaced by a drive wheel) instead of or in addition to thedrive wheel 24. As another example, in some embodiments, thetrack assembly 16 i may comprise more or less roller wheels such as the roller wheels 28 1-28 10. As yet another example, rather than have a generally triangular configuration as in this embodiment, in some embodiments, thetrack assembly 16 i may have various other configurations (e.g., a generally oblong configuration). - The
endless track 22 provides traction to theconstruction vehicle 10 on the ground. Theendless track 22 comprises aninner side 25 facing thewheels endless track 22 in which these wheels rotate. Theendless track 22 also comprises a ground-engagingouter side 27 engaging the ground on which theconstruction vehicle 10 travels and comprising atread pattern 40 to enhance traction of theconstruction vehicle 10 on the ground. - Motion of the
endless track 22 is imparted by thedrive wheel 24. In this embodiment, thedrive wheel 24 is a drive sprocket and theendless track 22 has a plurality of openings 33 1-33 N which cooperate with teeth of thedrive wheel 24 in order to drive theendless track 22. Theendless track 22 may interact with thedrive wheel 24 in other ways in other embodiments to be moved in its endless path. For example, in some embodiments, theinner side 25 of theendless track 22 may comprise a plurality of drive lugs that interact with thedrive wheel 24 in order to cause theendless track 22 to be driven, or may frictionally engage thedrive wheel 24 to cause theendless track 22 to be frictionally driven. - As the
endless track 22 is driven by thedrive wheel 24, the roller wheels 28 1-28 10 roll on theinner side 25 of a lower run of theendless track 22 to apply it on the ground. More particularly, the roller wheels 28 1-28 10 respectively roll on rolling surfaces 30 1, 30 2 of theinner side 25 of theendless track 22. - With additional reference to
FIGS. 3 to 10 , in this embodiment, theendless track 22 comprises a body ofelastomeric material 42, a plurality of cores 44 1-44 N at least partially embedded in theelastomeric material 42, and a layer oflongitudinal cables 31 embedded in theelastomeric material 42. Theendless track 22 may comprise one or more additional components, such as, for instance, one or more layers of reinforcing fabrics embedded in theelastomeric material 42. - The
elastomeric material 42 allows theendless track 22 to elastically change in shape as it is driven by thedrive wheel 24 in its endless path around thewheels elastomeric material 42 includes rubber. Various rubber compounds may be used. In some cases, different rubber compounds may be present in different areas of theendless track 22. Theelastomeric material 42 may also include one or more other substances in addition to the rubber. In other embodiments, theelastomeric material 42 may include other elastic substances resembling rubber. - The layer of
longitudinal cables 31 enhances strength in tension of theendless track 22 along a direction generally parallel to alongitudinal axis 45 of theendless track 22. In this embodiment, the layer oflongitudinal cables 31 comprises a plurality of steel cords adjacent to one another and extending generally parallel to thelongitudinal axis 45 of theendless track 22. Other types of cables (e.g., made of other metallic or composite materials) may be used in other embodiments. - The cores 44 1-44 N are distributed along and extend transversally to the
longitudinal axis 45 of theendless track 22 to impart transverse rigidity to theendless track 22. The cores 44 1-44 N also implement wheel guides to guide some of thewheels endless track 22 is driven by thedrive wheel 24. - More particularly, each core 44 i (1≦i≦N) comprises a pair of
wings wheel guide 52. In this embodiment, thecore 44 i, including thewings wheel guide 52, is made of metal (e.g., steel) formed into shape by casting. The core 44 i may comprise various other components, may be made of various other strong materials, and/or may be made using various other processes (e.g., forging, welding, fastening, etc.) in other embodiments. - The
wings longitudinal axis 47 of the core 44 i, which is transverse to thelongitudinal axis 45 of theendless track 22, to impart transverse rigidity to theendless track 22. Each of thewings top surface 53 oriented towards theinner side 25 of theendless track 22 and abottom surface 55 oriented towards the ground-engagingouter side 27 of theendless track 22. In this embodiment, each of thewings top surface 53 converges longitudinally outwardly towards itsbottom surface 55. Thewings - The
wheel guide 52 serves to guide some of thewheels endless track 22 is driven by thedrive wheel 24 to move theconstruction vehicle 10. As further discussed below, thewheel guide 52 is designed to enhance a wear resistance of theendless track 22, particularly its resistance to wear due to the roller wheels 28 1-28 10 rolling on itsinner side 25. - More particularly, in this embodiment, the
wheel guide 52 comprises a pair of guide projections 56 1, 56 2 that project on theinner side 25 of theendless track 22. Each guide projection 56 i (i=1 or 2) comprises atop end 57, abase 58, and a pair of wheel-facingsides top end 57. - The wheel-facing
side 60 of each guide projection 56 i faces thedrive wheel 24 and theidler wheels - The wheel-facing
side 62 of each guide projection 56 i faces respective ones of the roller wheels 28 1-28 10 as they pass next to that guide projection. In this case, the wheel-facingside 62 of the guide projection 56 1 faces the roller wheels 28 1-28 5, while the wheel-facingside 62 of the guide projection 56 2 faces the roller wheels 28 6-28 10. - For ease of reference, the wheel-facing
side 62 of the guide projection 56 1 will be further discussed below, with an understanding that, in this embodiment, the wheel-facingside 62 of the guide projection 56 2 is similarly designed. - The wheel-facing
side 62 of the guide projection 56 1 comprises anupper surface 68 and alower surface 70. Thelower surface 70 recedes inwardly from theupper surface 68 to form arecess 74. As will be further discussed, in this embodiment, as a portion of theelastomeric material 42 covering theupper surface 68 is worn out under action of the roller wheels 28 1-28 5, thelower surface 70 impedes passage of grit between itself and an adjoining portion of theelastomeric material 42, thereby enhancing a wear resistance of theendless track 22. - More specifically, in this embodiment, the
endless track 22 is manufactured such that, when new, aportion 69 of theelastomeric material 42 covers theupper surface 68 of the guide projection 56 1. Theportion 69 is a relatively thin layer of elastomeric material which is expected to wear out relatively quickly as the roller wheels 28 1-28 5 roll on the rolling surface 30 1 of theinner side 25 of theendless track 22. Indeed, as they roll on the rolling surface 30 1, the roller wheels 28 1-28 5 may continuously or frequently apply pressure and/or frictional forces on theportion 69 of theelastomeric material 42 that can induce its wearing. - This wearing effect may be accelerated when grit, from the environment of the
construction vehicle 10, lodges itself between the roller wheels 28 1-28 5 and theportion 69 of theelastomeric material 42. Grit refers to rocks (e.g., gravel), sand, and/or other small granular abrasive objects. In some cases, grit may be contained in water and/or other liquid (e.g., oil) that forms grit-containing media. - As the wearing effect continues, some or all of the
portion 69 of theelastomeric material 42 may be completely worn out, leaving at least part of theupper surface 68 of the guide projection 56 1 exposed. With additional reference toFIG. 11 , there is shown an example of a situation in which at least a portion of theupper surface 68, in this case, an entirety of theupper surface 68, has become exposed due to wearing out of theportion 69 of theelastomeric material 42 that originally covered it. - With the
endless track 22 in this state, as they continue to roll on the rolling surface 30 1, the roller wheels 28 1-28 5 can contact theupper surface 68 of the guide projection 56 1. Theupper surface 68 of the guide projection 56 1 can thus be viewed as a wheel-contacting surface, i.e., a surface designed to contact the roller wheels 28 1-28 5. - In this state, the
lower surface 70, which recedes inwardly from theupper surface 68 to form therecess 74, impedes passage of grit between thelower surface 70 and aportion 75 of theelastomeric material 42 adjoining thelower surface 70. In particular, while theupper surface 68 is contactable by (i.e., can contact) the roller wheels 28 1-28 5, thelower surface 70 and therecess 74 it forms are uncontactable by (i.e., cannot contact) the roller wheels 28 1-28 5. In other words, in this case, thelower surface 70 and therecess 74 it forms prevent the roller wheels 28 1-28 5 from contacting the wheel-facingside 62 below a certain level, namely a top edge 41 of therecess 74, at which thelower surface 70 starts receding inwardly from theupper surface 68. This absence of contact between the roller wheels 28 1-28 5 and the wheel-facingside 62 below the top edge 41 of therecess 74 makes it considerably more difficult for the roller wheels 28 1-28 5 to push grit between thelower surface 70 and theportion 75 of theelastomeric material 42 adjoining thelower surface 70. - The
lower surface 70 can thus be viewed as a sealing surface, i.e., a surface designed to prevent or at least limit passage of grit between itself and the adjoiningportion 75 of theelastomeric material 42. This impediment to passage of grit slows down a rate of wear of theendless track 22, thereby helping to retain proper adhesion between the core 44 i and theelastomeric material 42. - More particularly, in this embodiment, the
upper surface 68 defines anoverhang 72 extending over therecess 74. Theportion 75 of theelastomeric material 42 is in therecess 74 and protected by theoverhang 72. The roller wheels 28 1-28 5 are thus prevented from contacting the wheel-facingside 62 below theoverhang 72. - The
upper surface 68 comprises aprotrusion 80 for contacting the roller wheels 28 1-28 4. In this embodiment, theprotrusion 80 is located in a central region of theupper surface 68, protrudes increasingly in a downward direction, and has a bottom edge 81 vertically spaced from thetop surface 53 of thewing 50 1 to define theoverhang 72. The bottom edge 81 of theprotrusion 80 corresponds to the top edge 41 of therecess 74. - The
recess 74 has a depth D in a direction generally parallel to thelongitudinal axis 47 of thecore 44 i. The depth D may take on various values to allow enhanced wear resistance while maintaining structural integrity of the guide projection 56 1. For example, in some embodiments, when considering a thickness T of the guide projection 56 1 in a direction generally parallel to thelongitudinal axis 47 of the core 44 i at the top edge 41 of therecess 74, a ratio of the depth D to the thickness T may be at least 0.05, preferably at least 0.10, more preferably 0.20, and even more preferably at least 0.30. For instance, in some embodiments, the depth D may be at least 1 mm, preferably at least 5 mm, and more preferably at least 10 mm. - The
recess 74 also has a width Wr in a direction generally parallel to awidthwise axis 49 of the core 44 i at the top edge 41 of therecess 74. The width Wr may take on various values. For example, in some embodiments, the width Wr of therecess 74 may be at least one quarter, preferably at least one third, and more preferably at least one half of a width Ws of the wheel-facingside 62 in a direction generally parallel to thewidthwise axis 49 of the core 44 i at the top edge 41 of therecess 74. - Upon receding inwardly to form the
recess 74, in this embodiment, thelower surface 70 of the guide projection 56 1 extends outwardly to merge with thetop surface 53 of thewing 50 1. - It will thus be appreciated that, in this embodiment, the wheel-facing
side 62 of each guide projection 56 i enhances the wear resistance of theendless track 22 by impeding passage of grit between itslower surface 70 and theportion 75 of theelastomeric material 42 adjoining itslower surface 70, thereby helping to retain proper adhesion between the core 44 i and theelastomeric material 42. - The
endless track 22, including the cores 44 1-44 N, may be configured in various other ways in other embodiments. - For example, in some embodiments, the
endless track 22 may be manufactured such that, when new, theelastomeric material 42 does not cover some or all of theupper surface 68 of each guide projection 56 i, which is rather exposed. - As another example, in other embodiments, the guide projections 56 1, 56 2 of the
wheel guide 52 of each core 44 i may have various other configurations. In particular, theupper surface 68 and thelower surface 70 of the wheel-facingside 62 of each guide projection 56 i may be configured in various other ways. For instance, therecess 74 defined by thelower surface 70 may have various other shapes. Also, theprotrusion 80 of theupper surface 68 may have a different shape or theupper surface 68 may not comprise any protrusion at all. For instance,FIGS. 12 and 13 show an example of an embodiment in which the guide projection 56 1 does not comprise any protrusion on itsupper surface 68 and in which itslower surface 70 and therecess 74 it forms have another shape. - As yet another example, in other embodiments, the
construction vehicle 10 may comprise a different arrangement of roller wheels such as the roller wheels 28 1-28 10 which may be such that the wheel-facingside 60 of each guide projection 56 i, instead of or in addition to the wheel-facingside 62 of the guide projection 56 i, faces roller wheels. In such embodiments, the wheel-facingside 60 may be configured as discussed previously in respect of the wheel-facingside 62. - As yet another example, in other embodiments, the
wheel guide 52 of each core 44 i may comprise any number of guide projections (i.e., a single one, two, three or more) such as the guide projections 56 1, 56 2 that may be located at other positions along thelongitudinal axis 47 of thecore 44 i. - Although in this embodiment the wheel-facing
side 62 of the guide projections 56 1, 56 2 of each core 44 i enhances the wear resistance of theendless track 22 under action of the roller wheels 28 1-28 10, in other embodiments, the wheel-facingside 60 and/or the wheel-facingside 62 of each of the guide projections 56 1, 56 2 may be similarly configured with a recess similar to therecess 74 in order to enhance the wear resistance of theendless track 22 under action of other wheels of theconstruction vehicle 10. For example, in some embodiments, the wheel-facingside 60 and/or the wheel-facingside 62 of each of the guide projections 56 1, 56 2 may have a recess similar to therecess 74 to impede passage of grit between that wheel-facing side and a portion of the elastomeric material in such a recess due to action of thedrive wheel 24, thefront idler wheel 26, and/or therear idler wheel 29. - While in this embodiment the
work vehicle 10 is a construction vehicle designed to perform construction work, in other embodiments, thework vehicle 10 may be an agricultural vehicle (e.g., a harvester, a combine, a tractor, etc.) designed to perform agricultural work, a forestry vehicle (e.g., a feller-buncher, a tree chipper, a knuckleboom loader, etc.) designed to perform forestry work, a military vehicle (e.g., a combat engineering vehicle (CEV)) designed to perform work in a military application, or any other work vehicle designed to perform another type of work (e.g., mining, geophysical surveying, etc.) in off-road conditions. In such embodiments, thework vehicle 10 may be equipped with various types of working implements depending on the nature of the work to be performed (e.g., a combine head for an agricultural vehicle, a mulching head for a forestry vehicle, etc.). - Although various embodiments and examples have been presented, this was for the purpose of describing, but not limiting, the invention. Various modifications and enhancements will become apparent to those of ordinary skill in the art and are within the scope of the invention, which is defined by the appended claims.
